The No. 30 NGT Motorsport Porsche GT3, driven by Sean Edwards, moved to the front of the pack in the GT division – holding a 19.5-second lead over Oliver Jarvis in the Alex Job Racing's No. 24 Audi R8. The Bum Rum Racing No. 13 Audi, driven by Markus Winkelhock, was in third.

The Napleton Racing No. 16 Porsche Cayman remained in front of the GX class, with the BGB No. 38 Porsche Cayman three laps behind in second.

12 A.M. UPDATE

Eight hours into the Rolex 24 and pole-sitter Scott Pruett is back out in front the field.

Pruett's No. 01 TELMEX/Target Chip BMW Riley Daytona Prototype led under full-course caution after Kevin Estre's No. 18 Nehiner Motorsports American Porsche went off at Turn 5 and could not get going – bringing out the yellow.

There were eight Daytona Prototypes on the lead lap. The overall lead had changed hands 10 times.

While there was plenty of bumping and banging around the 3.56-mile road course, there had been only three full-course cautions.

10 P.M. UPDATE

Six hours into the Rolex 24 the No. 01 Ganassi Racing BMW Riley continued its assault over Daytona International Speedway's 3.56-mile road course.

The No. 01 machine had turned 192 laps while the crew performed flawless pit stops, including front brake pad changes in under two minutes.

The No. 10 Corvette DP was giving chase, a little more than 14 seconds behind the leader.

The No. 69 Ferrari topped the GT class while the GX class had become a two-car battle between the No. 16 and No. 38 Porsche Caymans. They were 24 laps behind the overall leader, but in an intense duel for position.

9 P.M. UPDATE

With Juan Pablo Montoya at the wheel, the No. 01 Ganassi Racing BMW-Riley powered back to the lead in the Rolex 24 At Daytona, with a best lap time of 1.43.331.

Running in second was the No. 10 Corvette, driven by Ryan Hunter-Reay; followed by the No. 9 Corvette, driven by Mike Rockenfeller; the No. 99 Corvette driven by Jon Fogarty and the No. 2 Ford Riley, with Ryan Dalziel at the wheel.

Drivers stopping by the media center said the pair of Ganassi cars were clearly the fastest.

Allan McNish, who briefly led in the No. 2 Ford Riley, told the media: "I think it's quite clear we're not quick enough at the moment."

But at 9:30 p.m. the other Ganassi car, the No. 02 BMW Riley had dropped to sixth place.

8 P.M. UPDATE

The No. 2 Ford Riley, shared by Ryan Dalziel, Alex Popow, Sebastien Bourdais and Allan McNish, powered to the lead four hours into the twice-around-the-clock marathon.

While the No. 01 BMW Riley surrendered the lead, it was hardly dealt a knockout blow. The Daytona Prototype was 42.329 seconds behind the leader. That amounts to the blink of an eye in endurance racing.

Rounding out the top three was the No. 10 Corvette DP, virtually on the rear bumper of the No. 01 machine.

The No. 63 Ferrari continued to be best in GT class, while the GX leader was the No. 16 Porsche Cayman.

The defending race champion, the No. 60 Ford Riley, was crawling back into view after a lengthy pit stop in the first hour of competition. The No. 60 was 13th, four laps behind the leaders.

“We're running real good,” the four-time Rolex 24 winner said. “It takes two laps for the car to get going with new tires. You can carve your way through traffic. You have to pick your way through the (slower) GT cars.”

The No. 10 Corvette DP was second with Max Angelelli at the wheel.

“Our car is really good,” Angelelli said. “We'll see.”

The No. 63 Ferrari was top in the GT class, and the No. 16 Porsche Cayman was leading the GX class.

After two hours, Pruett averaged 123.930 mph over the 3.56-mile road course.

5 P.M. UPDATE

Scott Pruett didn't drive like a 52-year-old man at the start of the Rolex 24 At Daytona.

He was wheeling the pole-winning No. 01 Ganassi Racing BMW Riley like he stole the machine, gapping the second-place car by more than eight seconds in the first hour of competition.

Pruett logged 34 laps over the 3.56-mile road course. Only nine other Daytona Prototypes were scored on the lead lap. Pruett's average speed was a blazing 124.606 mph.

Defending Rolex 24 champion, the No. 60 Michael Shank Racing Ford Riley, went to the pits only 38 minutes into the race for repairs or as Grand-Am reported, “Almost an entire front end change.”

Scott Dixon, behind the wheel of the No. 02 Ganassi BMW Riley, was running second. The No. 6 Ford Riley was third in line.

John Potter was pacing the GT class in the No. 44 Porsche GT3 Cup while Shane Lewis was at the top of the new GX class. Lewis drives the No. 16 Porsche Cayman.

The infield at Daytona International Speedway was packed with fans, cars and RVs as the green flag dropped for the 51st running of the race.

The final grid showed a 57-car field, including 17 of the marquee Daytona Prototypes, which formed the front pack of cars. They are joined by 44 GT sportscars and six of the new GX class sedans.

The weather is ideal for an outdoor event. The sun is bright and the air temperature was a cool-feeling 77 degrees at the Speedway.

“The weather is perfect, the crowd is awesome,” Speedway president Joie Chitwood III said. “There's energy in the air. I think we are going to have a great race.”

Chip Ganassi Racing with Felix Sabates started the race with the top-two grid positions. Pruett started from the pole with the No. 02, piloted by Dixon, on the outside pole position.

Before the race started, racing icon A.J. Foyt made an appearance, and grand marshal Hurley Haywood, who has a record five Rolex 24 crowns, gave the command to fire engines.
